The Aquile are in crisis with just one Serie A victory in their last 10 and were jeered off the field on Thursday after a 0-0 Europa League draw with Trabzonspor.

“We need optimism and clear heads to play this game,” warned the Coach in his Press conference.

“We have been too unlucky in 2013 and need to analyse what went wrong. We must take it one day at a time and give our all to win the next game.

“It is difficult to give a definitive shake-up, as this up-and-down mentality has been going on for months. There should be more positivity from everyone, including the media.”

Lazio fans could be particularly furious with another slip-up on Sunday, as there is a strong rivalry with Livorno.

“This game is worth three points, just like the others. We want to win and turn what we’ve done recently into goals and points,” continued Petkovic.

“Livorno are a very good side who defend well, even though tomorrow I want to see a more productive Lazio.

“We need to prepare for this match by being aware of our strengths and emerging from this situation all together. The squad realised what they are risking and what they are going through, so it is important to all stick together.”
